Abstract

L'invention concerne un système de raffinage de verre (10), un dispositif de raffinage de verre (12) et un procédé. L'appareil (12) selon un aspect de l'invention comprend un objectif (14) ayant une extrémité latéralement extérieure (16), un courant de métal fondu (20) s'écoulant à partir d'une ouverture (18) dans l'objectif (14) et sur l'objectif (14), et se séparant de l'objectif (14) à un emplacement de séparation de métal fondu (22) qui est à l'intérieur de l'extrémité (16) ; et un réceptacle de métal fondu (32) disposé au-dessous de l'objectif (14) et conçu pour recevoir le courant de métal fondu (20), un courant de verre fondu (28) s'écoulant vers le bas en direction de l'objectif (1.4) et sur le courant de métal fondu (20), et le courant de verre fondu (28) se séparant du courant de métal fondu (20) à un emplacement de séparation de verre fondu (30) qui est latéralement à l'extérieur de l'emplacement de séparation de métal fondu (22) et s'écoulant dans un réceptacle de verre fondu (32).
